+===== Adding and using new servlet params =====
+To make this work I have modified the java code to store any initParams mentioned in the servlet definition (in servlets.xml) in the config_params HashMap. This gets passed to the transformer when it does the page transformation, so all of these get passed in as parameters. You can access them by declaring
+<xsl:param name="param-name"/> at the start of web/interfaces/default/transform/gslib.xsl along with the other predefined ones.
+<code>
+  <!-- some global parameters - these are set by whoever is invoking the transformation
+  Any servlet init parameters can be accessed by adding a param here-->
+  <xsl:param name="interface_name"/>
+  <xsl:param name="library_name"/>
+  <xsl:param name="site_name"/>
+  <xsl:param name="use_client_side_xslt"/>
+  <xsl:param name="filepath"/>
+  <xsl:param name="google_tracking_id"/>
+</code>
+Now that this has been implemented, instead of hard coding the tracking id in the xslt file, you can specify it as an initParam to a servlet (therefore each servlet can have a different one if need be)
+In web/WEB-INF/servlets.xml, add an init-param like the following to the main library servlet (specifying of course, your actual google id):
+<code>
+	<init-param>
+	  <param-name>google_tracking_id</param-name>
+	  <param-value>UA-xxx-1</param-value>
+	</init-param>
+</code>
+You will need to restart the server for this to take effect.
